Comprehensive Experiment on Synthesis of Pyridine Quaternary Ammonium Salt Picric Acid with Fluorescent and Antibacterial Dual Functions

A comprehensive experiment on the preparation and properties of pyridine quaternary ammonium salt picric was introduced. 4-Bromobenzyl pyridine quaternary ammonium salt picric acid (4BrBzPy]PIC]) is synthesized by using 4-bromobenzyl bromide, pyridine, picric acid and potassium carbonate as raw materials. It has been characterized by IR spectrum, UV-Vis spectrum, electrospray mass spectrometry, powder X-ray diffraction and single crystal X-ray diffraction. The fluorescent properties in solid state and antibacterial properties of the salt is investigated. The experiment project covers the multi-disciplinary knowledge and experiment operation technology, and has the characteristics of comprehensiveness and research. The project helps students to cultivate their comprehensive experimental ability and creative ability, and is suitable for undergraduate majors such as applied chemistry, material chemistry and materials science and engineering as comprehensive experiment project.
